If GRUB can't locate your root or /boot file system by UUID, then we would need to know how you partitioned everything. Did you try to do LVM, RAID, or any combination of them? Is the root or /boot file system inside one of those, or is it on a native partition? What file system type did you use to create it? Is this an EFI system or Legacy boot?
